Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
Answer: the answer is 196
Step-by-step explanation:
(2,3) if you plug in the Y you get 3 on the left side and then you plug in 2 and get 3*2 - 3 which is 6-3 when is 3 as well . So both values on either side are equivalent
1/6 because there are 6 numbers on that die and there is only one 5
Answer:
The answer is 4144.
Step-by-step explanation:
We have to find the maximum value of f(x)= 
when 
We can write as 
Substituting the value of y
= ![3x^{2}(8-x)^{2}[-x+8-x]+3[-x+8-x]](https://tex.z-dn.net/?f=3x%5E%7B2%7D%288-x%29%5E%7B2%7D%5B-x%2B8-x%5D%2B3%5B-x%2B8-x%5D)
= ![3(8-2x)[x^{2}(8-x)^{2}+1]](https://tex.z-dn.net/?f=3%288-2x%29%5Bx%5E%7B2%7D%288-x%29%5E%7B2%7D%2B1%5D)
For maximum, we will equate the equation to 0.
And we get,
=> x = 4
And as
> y = 4
So, we will put these values in equation to get maximum value.
